The study examines the interplay among corporate carbon risk, voluntary disclosure, and cost of capital within the context of South Africa, a “rising power” in the climate policy debate. We develop a system of simultaneous equations models and analyze data drawn from firms traded on the Johannesburg Securities Exchange (JSE), for the period 2010 to 2015, using the three‐stage least squares procedure. We find that voluntary carbon disclosure is associated with lower overall (and equity) cost of capital, after controlling for corporate carbon risk. We also find that firms with higher carbon risk tend to provide better quality carbon disclosure and signal the possibility of high carbon risk to avoid negative market reactions resulting from concealing carbon information. Although the capital market does not appear to incorporate individual firm's carbon risk exposure into the required cost of capital, we find that it generally requires higher returns for companies operating in carbon‐intensive sectors. These findings suggest that firms could exploit the virtues of voluntary carbon disclosure to reduce their overall (and equity) cost of capital. Our findings also imply that regulators and policymakers could point to the cost of capital reducing role of voluntary disclosure to lure firms into voluntarily providing superior quality carbon disclosures.

Purpose Although proponents of integrated reporting (IR) advocate that this emerging practice has the potential to transform corporate reporting, the eventuation of this expectation would depend on the incentive IR provides to firms. This study aims to examine whether IR is associated with cost of debt and whether IR moderates the relationship between financial reporting quality and cost of debt. Design/methodology/approach Based on insights drawn from information asymmetry and agency theories, the authors develop models that link IR and financial reporting quality with a firm’s cost of debt. The authors analyze 847 firm-year observations drawn from non-financial firms traded on the Johannesburg Stock Exchange, for the period between 2009 and 2015. Findings The authors find that firms that provide integrated reports tend to have a lower cost of debt than those do not provide IR. The authors also find an inverse association between financial reporting quality and cost of debt, and that integrated reports accentuate this association. The findings suggest that the debt market perceives value in the information presented in integrated reports beyond what is furnished in financial reports. Originality/value To the best of the authors’ knowledge, this study is the first to document evidence suggesting that the debt market perceives value in the information presented in integrated reports, beyond what is furnished in financial reports.

Purpose – The purpose of this paper is to examine the role of institutional, macroeconomic, industry, and firm characteristics on the adjustment speed of corporate capital structure within the context of developing countries. Design/methodology/approach – The authors considers a sample of 986 firms drawn from nine developing countries in Africa over a period of ten years (1999-2008). The study develops dynamic partial adjustment models that link capital structure adjustment speed and institutional, macroeconomic, and firm characteristics. The analysis is carried out using system Generalized Method of Moments procedure which is robust to data heterogeneity and endogeneity problems. Findings – The paper finds that firms in developing countries do temporarily deviate from (and partially adjust to) their target capital structures. Our results also indicate that: more profitable firms tend to rapidly adjust their capital structures than less profitable firms; the effects of firm size, growth opportunities, and the gap between observed and target leverage ratios on adjustment speed are functions of how one measures capital structure; and adjustment speed tends to be faster for firms in industries that have relatively higher risk and countries with common law tradition, less developed stock markets, lower income, and weaker creditor rights protection. Research limitations/implications – Future research should focus on examination of the adjustment speed of debt maturity structure. Identification of industry-specific characteristics that affect the pace with which firms adjust their capital structure to the optimum is another possible avenue for future research. Practical implications – Our findings have practical implications for corporate managers, governments, legislators, and policymakers. Originality/value – The study focuses on firms in developing countries for which the literature on adjustment speed of capital structure is virtually non-existent. Furthermore, unlike previous works on capital structure, it explicitly models industry variable as one of the determinants of adjustment speed. Therefore, it contributes to the literature on capital structure and adjustment speed in general and to the literature on developing countries in particular.

The study examines whether corporate carbon risk exposure is associated with financial reporting quality and whether voluntary carbon disclosure mediates the relationship. We analyze data drawn from firms traded on the Johannesburg Stock Exchange (JSE), for the period 2011 to 2015. We document robust evidence that firms with higher carbon risk exposure tend to provide financial statements of poorer quality (i.e., direct effect) and this association is partially mediated through voluntary carbon disclosure (i.e., indirect effect). The overall negative association between corporate carbon risk exposure and the firm's financial reporting quality is partly explained by the quality of voluntary carbon disclosure.
